+Autonomous task refinement using Stop hooks. Claude works on a task until completion.
+
+**Commands:**
+${commands_table}
+
+**How it works:**
+1. You provide a prompt with clear completion criteria
+2. Claude works on the task
+3. Stop hook intercepts exit, re-feeds prompt
+4. Loop continues until \`<promise>TEXT</promise>\` found or max iterations
+
+**Example:**
+\`\`\`
+/ralph-wiggum:ralph-loop \"Build REST API. Output <promise>DONE</promise> when tests pass.\" --completion-promise \"DONE\" --max-iterations 20
+\`\`\`
